According to the IMDB, Robert Altman (the sort of filmmaker who is mentioned in terms of movies he made over three decades ago; “Altman, the director of M*A*S*H and Nashville, is…”) is making a film based on Garrison’s Keillor’s Prairie Home Companion radio show. It will star Lindsey Lohan, Meryl Streep, Kevin Kline, Lily Tomlin, Woody Harrelson, Tommy Lee Jones Keillor himself. Realizing this might not be a huge urban hit*, Altman cannily has commented that he hopes it will draw much the same audience as “Mel Gibson’s Jesus picture.”
Yes, it sounds like he has that market demographic zeroed in on.
[*Untrue, actually, since his best bet is with upper middle class urban liberals, the sort of people who listen to NPR and the Prairie Home Companion in the first place.]
